What Are Blue Caribbean Cupcakes?

These cupcakes are inspired by the classic Blue Caribbean cocktail—a sweet, fruity drink that transports you straight to a white sandy beach. I’ve taken that tropical essence and packed it into a soft, moist vanilla-pineapple cupcake, then crowned each one with a stunning ombré swirl of blue frosting. The finishing touches? A sprinkle of toasted coconut, a pineapple wedge, a cherry, and of course, a little umbrella because why not go full island mode?

Reasons to Love This Recipe

• Tropical Vibes in Every Bite: The pineapple and coconut combo brings vacation energy to your kitchen.
• Stunning Presentation: That ocean-blue swirl and fruity garnish? Instant showstopper!
• Perfect for Summer Parties: BBQs, birthdays, pool days, or luau-themed events—these belong at every one.
• Customizable Flavor: Want them boozy? Add Blue Curaçao. Want kid-friendly? Use blue punch!

What Do They Taste Like?

Imagine biting into a soft, airy cupcake with hints of pineapple juice and coconut extract—it’s bright, sweet, and tropical. The frosting adds buttery richness and more fruity flair, with a vanilla-coconut backbone and just a touch of tang if you opt for pineapple juice over milk. The toasted coconut on top adds crunch and warmth, while the garnishes bring freshness and fun.

How to Make Blue Caribbean Cupcakes (Step-by-Step)

Step 1: Make the Cupcakes

1. Preheat your oven to 350°F (175°C) and line your cupcake tin with fun, tropical-themed liners.
2. In a large bowl, whisk together the cake mix, eggs, oil, water, pineapple juice, coconut extract, and optional blue curaçao or punch.
3. Beat the mixture for about 2 minutes until smooth and creamy.
4. Fill each cupcake liner about 2/3 full.
5. Bake for 18–22 minutes or until a toothpick comes out clean.
6. Let them cool completely before frosting.

Step 2: Make the Frosting

1. Beat the softened butter until pale and fluffy (about 2–3 minutes).
2. Gradually add in powdered sugar, 1 cup at a time.
3. Mix in the pineapple juice or milk and coconut extract until you reach your desired consistency.
4. Divide frosting into two or three bowls and tint each one with varying shades of blue using gel food coloring.
5. Using a piping bag, fill with the different shades side-by-side for a gorgeous ombré effect.

Step 3: Decorate Like a Tropical Pro

1. Pipe tall swirls of blue frosting onto your cooled cupcakes.
2. Sprinkle with toasted shredded coconut.
3. Top with a pineapple wedge, maraschino cherry, and—of course—a mini umbrella or palm pick!

What to Serve with Blue Caribbean Cupcakes

These cupcakes are fabulous on their own but pair beautifully with:

• Fresh tropical fruit salad (think mango, kiwi, and dragonfruit)
• A round of actual Blue Caribbean cocktails or mocktails
• Coconut-lime sorbet or vanilla ice cream
• Grilled pineapple skewers
• Sparkling lemonade with mint and berries

Tips for Making the Best Blue Caribbean Cupcakes

• Don’t overmix the batter—it keeps the texture light and fluffy.
• Use gel food coloring for vibrant color without thinning the frosting.
• Let cupcakes cool completely before frosting—trust me, melted frosting is never cute.
• Stripe your piping bag by spooning different blues along the sides for that signature ocean swirl.

How to Store These Cupcakes

• At Room Temperature: In an airtight container for up to 2 days.
• In the Fridge: Store for up to 5 days, but let them sit at room temp 30 minutes before serving.
• Freezing: Unfrosted cupcakes can be frozen for up to 3 months. Wrap tightly and thaw before frosting and serving.

Frequently Asked Questions

Can I make these cupcakes ahead of time?

Absolutely! Bake the cupcakes a day ahead and store them unfrosted. Frost the day of your event for best presentation.

Can I use canned pineapple juice?

Yes! Canned or bottled juice works perfectly in both the batter and frosting.

What’s the best way to get that swirled frosting look?

Divide your frosting into separate shades of blue, then spoon them side by side into your piping bag. Use a large star tip to create beachy waves!

Can I make these into a cake instead of cupcakes?

Totally! Just adjust the baking time to 25–35 minutes for a 9×13 pan, and check doneness with a toothpick.
